Agronomic Soil Suitability Test
pH, salinity, types and concentrations of soluble salts (calcium, magnesium, chloride, sodium, sulfate, phosphate, boron, and nitrate) in saturation extract, SAR, all essential nutrients, percent moisture, half saturation and 14 non-essential, potentially toxic trace minerals.
Essential nutrients – boron, calcium, chloride, copper, iron, magnesium, manganese, molybdenum, nitrogen, nickel, phosphorus, potassium, sulfur, zinc and for some plants sodium.
Non-essential minerals – aluminum, arsenic, barium, cadmium, chromium, cobalt, lead, lithium, mercury, selenium, silver, sodium, strontium, tin, titanium, and vanadium.
